SPECIFICATION formingpart of Letters Patent N0. 776,096, dated November 29, 1904.

Application filed May 16, 1904. Serial No. 208,238- (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK S'rRA'urNnR, a citizen of the United States, residing atSalisbury, in'the county of WVicomico and State of Maryland, have invented certain new and use ful Improvements in Motors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to motors adapted to be primarily operated by the exhaust of a locomotive or other engine.

The object of the invention is to provide a motor of this character which may be placed in the smoke-box or other suitable place on a locomotive and arranged to receive the impact of the exhaust-steam of said engine, whereby the same is driven, means being also provided whereby live steam may be applied to run the motor when the locomotive is not running.

With these and other objects in view the in vention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view through the smoke-box of a locomotive, showing the Fig. 2 is a cross-sectional view through the same on a line with the exhaust-pi pes and stack and looking toward the front end of the locomotive. Fig. 3 is a horizontal sectional view taken on a line with the shaft of the motor, and Fig. 4; is a vertical cross-sectional View showing a modified construction of motor.

Referring more particularly to the drawings, 1 denotes the smoke-box of a locomotive.

2 denotes the exhaust-steam pipes leading from the cylinders. (Not shown.)

3 denotes the stack.

Within the smoke-box is suitably mounted a turbine-motor casing at, divided into two compartments 5 and 6, in which are located steam turbine-wheels 7 and 8, fixedly mounted upon a common shaft 9, the ends of which pass through the sides of the smoke-box and are journaled in bearings fixed on the outer side of the same.

In one side of the motor-casing is formed two slots 10 and 11, each of which opens into one of the compartments 5 and 6. The slots 10 and 11 also communicate with verticallydisposed comically-shaped tubes 12 and 13, which form steam passages or channels, said tubes communicating at their upper ends with the smoke'stack 3. Into the lower end of the tube 12 projects the upper ends of steam-exhaust pipes 2 from the cylinders of the engine. into the lower end of the tube 13 projects the end of a live-steam pipe 15, which extends to and is connected with the engine or locomotive boiler. The pipe 15 is provided with a suitable valve (not shown) whereby the passage of steam through the same may be controlled by the engineer.

-The shaft of the turbine-wheels is so arranged in the casing l that the ends of the blades of said wheels project through the slots 10 and 11 and into the tubes 12 and 13, so that the steam in passing through said tubes will engage the blades of the wheels, and thereby drive the same. The casing 4 is preferably rounded on one side and is formed in two parts, the flanged edges of which are bolted together, as shown.

One end of themotor-shaft 9 is squared and is adapted to be engaged with a socket 16 on the end of the drive-sliiaft 17 of a dynamo 18 or other appliance mounted on the side of the locomotive by which electricity may be generated for lighting the cars, operating fans in the same, or for any other purpose.

on the outer side of the smoke-box, at the opposite end of the motor-shaft, is secured a bracket 19, to which is pivotally connected the upper end of a shifting-lever 20, which is loosely connected to the motor-shaft 9 between two collars 21, fixed on said shaft, whereby upon swinging said lever in one direction or the other said shaft will be shifted in its hearings to bring the squared end of the same into and out of engagement with the driveshaft of the dynamo 18. The lower end of the lever 20 is adapted to work in a curved slotted guide arm or bracket 2 which is provided with a set-screw 23, whereby said lever may be held in position, thereby locking the motor-shaft in engagement with the dynamoshaft.

On the casing 4t and working through the steam-tube 12 is arranged a curved laterallysliding valve-plate 24, which is adapted to be shifted in and out through the said tube 12 to cover and uncover the slot 10 and the turbinewheel in said tube, thereby cutting the same off from the said tube and causing the exhauststeam to pass through the tube 12 and out of the stack without engaging the blades of the wheel 7 To one end of the plate or valve 24: is secured the inner end of a shifting-rod 25, which projects through the side of the smokeboX and is provided with a handle or knob whereby the same may be operated to shift said valve-plate and cut the steam off of the motor. The motor-wheels may be arranged at the upper ends of the tubes 12 and 18, or they may be arranged at points between the ends thereof, as here shown. I do not desire to limit myself in this particular.

In Fig. 4: of the drawings is shown a modified construction of motor. In this instance the valve-casing 1 and steam-tubes 12 and 18 are done away with, and in lieu thereof a turbine-wheel 25 is placed in the stack of the 10- comotive. The turbine-wheel 25 consists of a vertically-disposed shaft 26, mounted in bearings 27 in the stack 3 and provided with spirally-arranged bolts 28, as shown. On the lower end of the shaft 26 is a beveled gearpinion 27, which meshes with the pinion 28, fixed on the end of a shaft 29 of a dynamo or similar device, which is not here shown.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is"

1. A motor comprising a casing arranged in the smoke-box of a locomotive and divided into two compartments each having a steampassage on one side, a revoluble shaft extending through said compartments, motor-wheels on said shaft, one in each compartment and extending to one of said steam-passages for rotation by steam passing through the latter, a valved live-steam pipe discharging into one of said passages, an exhaust-steam pipe discharging into the other, and means to cut off the exhaust-steam from the motor-wheel in the exhaust-steam passage without closing the latter.

2. A motor comprising a casing arranged in the smoke-box of a locomotive, slots formed in one side of said casing, a motor-shaft arranged in the same and passing through the side walls of said smoke-box, turbine-wheels fixedly mounted on said shaft, the outer ends of the blades of said wheels being adapted to project through said slots, exhaust-steam tubes arranged on said casing and adapted to receive the ends of said turbine-wheel blades whereby the same are driven by the exhauststeam of said locomotive, substantially as described.

3. A motor comprising a casing arranged in the smoke-box, of a locomotive, slots formed in one side of said casing, a motor-shaft arranged in the same, the ends of said shaft passing through the sides of said smoke-box, turbine-wheels fixedly mounted on said shaft, the outer ends of the blades of said wheels being adapted to project through said slots, vertically-disposed conically-shaped tubes secured to the outer side of said casing and adapted to receive the ends of said turbine-wheel blades, the lower ends of one of said tubes engaging the end of the exhaust-steam pipes of the locomotive and the lower end of the other tube being adapted to receive the end of a valved live-steam pipe, whereby said turbinewheels are driven by the exhaust or live steam from said locomotive, means whereby said turbine-wheels are out 01f from the action of said exhaust and live steam, and means whereby said motor-shaft is engaged and disengaged with a motor-driven element, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
